Texas Instruments TCAN1462x-Q1 Automotive SIC CAN FD Transceivers

Texas Instruments TCAN1462x-Q1 Automotive SIC CAN FD Transceivers meet the physical layer requirements of the ISO 11898-2:2016 high speed CAN specification and the CiA 601-4 Signal Improvement Capability (SIC) specification. The device reduces signal ringing at the dominant-to-recessive edge and enables higher throughput in complex network topologies. Signal Improvement Capability allows the applications to extract the real benefit of CAN FD (flexible data rate) by operating at 2Mbps, 5Mbps, or even beyond in large networks with multiple unterminated stubs.

The TCAN1462x-Q1 meets the timing specifications mandated by CiA 601-4, providing much tighter bit timing symmetry compared to a standard CAN FD transceiver. This provides a larger timing window to sample the correct bit and enables error-free communication in large complex star networks where ringing and bit distortion are inherent.

The TI TCAN1462x-Q1 CAN FD Transceiver is available in 8-pin SOT-23, VSON, and SOIC packages and is AEC Q100 Grade 1 qualified for use in automotive applications.
